Be it known that I, JOSEPH P. EOK, a citizen of the United. States,residing at Muncie, in

the county of Delaware and State of Indiana,

have invented a certain new and useful Irn-' provement in ElectricalApparatus for Oharg known as open-hearth? furnaces, with scrap or otheriron and has for its object to provide a simple-and effective device forbringing about the several'opera'tion's necessary to perform the desiredfunction .Tby a series of electrical motors, which are put under easycontrol of the 0perator;lwho stands upon a platform carried by':thetraveling crane or charging-frame. I1

With these ends in viewthis invention consists in the details ofconstruction and comwhich this invention'appertains may undera' binationof elements hereinafter set forth and then specifically;designated-bythe claims. 1: In order that those skilled in the art tostand how to make and use'the same, the construction andoperat-ion willnow be described in detail, referring to the accompanying drawings,forminga part of .this specifi-- cation, in which- Figure 1 is anelevation of an apparatus made in accordance with myimprovement, the

stationary supporting-tracks being in section Fig. 2; Fig. 4:, a sectionof a pOrtiOnof th'e' traveling crane, taken longitudinally through thecharger-bar, showing the interior thereof; and-galcamqodafor locking thecharging-pan to theouterlend of:zthis. bar; Fig. 5, a plan view .of thecharger-tracks anditruck-frame adapted to run'thereon, and also themechanism;for causing the charger-truck tracks to by means of th1sgearing.

move upon the supporting-tracks, so as to brin'glthe charger in itsproper position relative' to the various doors of the furnace; Fig. 6,an enlarged section at the line 2, showing the oscillating casting androller bearing through "which'the charger-bar passes; Fig; 7, anenlarged section of the outer end of the charger- I bar, illustratingthe locking-cam holding the pan in position; and Fig. 8, across-sectionof theouter end of. the charger-barvupon a line I; with this cam,'thecam being turned upward inits locking position. Y

. In carrying out my invention as here embodied, K:is a trackrunningupon a runway L for carrying an electric crane. Each end of.track'K is carried upon a truck P. The lmachine'r'y for driving thesetrucks consists of a motor M and spur-wheels located at 9 or the backendof track K. The trucks are connected: by a shaft K, running the fulllength ofpthe track. This track may be carried from one end of therunway to the other Upon the track K'is located a charger-truck frame Aand A D is the motor for driving the charger-truck carrying the loadintothe furna'ceand withdrawingithe charging-bar. 1 I The'spur-wheelsl). andD are connected to the shaft of the charger} truck. Spurwheel D? is madefast to the front'axle of the charger-truck and turns the flange-wheelsD B is a hollow shaft used as'a charging-bar. Within this shaft is asmall shaft orrod 0, on oneend of." whichis made fast a hand-wheel O. Attheiother end is aneccentric cam G, which by turning thehand-wheel O isturned 7 within the, shaftorfextended through a notch in the wall of theshaft at the top, as shown in Fig; 7. 1

G represents the charging-pan, upon the back end of which is a large'castin g, as shown. In this casting is a square .hole with a notch atthe'back end, which cam O is made toenter by. means ;of the hand-,.wheel- 0 after the charging-bar. is entered into the square hole.This looks the charging-pan ,upon'the charging-bar securely, so that itmaynot be off and left in the furnace. I

The charging-bar is supported-at' lfi by a casting H, which-is 'pivotedin casting-I, and casting I is bolted securely to A The chargdrawn IOOing-bar is made to turn on pin-bearings X, X being a bearing similar toX and located at '7. On the back end of the charging-bar I is keyed aworm -wheel J for turning the charging-bar. Meshing into J is a screw T,and T is turned with a shaft by motor F, which is located upon a bracketbolted to the carrier U. Carrier U has a wide pin-bearing and shelf formotor 1 and motor F lowers and raises with carrier U, and the connectingwire is so coiled from the controller to motor as to hang loose. CarrierU is made to move up and down in slide U by means of the shafts It, theupper ends of which are threaded.

Motor E operates a shaft upon which is keyed two screws Y. These screwsmesh into worm wheels V, which are screwed upon shafts R and held inplace by brackets, as shown in Fig. 2. This gearing raises and lowersthe back end of. the charging-bar I tilting the pan up or down.

N represents electric controllers.

l and 2 are field-wires stretched along one girder of the runway. Abracket-trolley supported from the truck I furnishes contact with thesefieldwires. 3 and I represent a second pair of field-wires strung alongthe charger-track. 5 and 6 represent another pair of field-wires alsoupon the charger-track. These are connected to the switchboard at A andfurnish current for motors D, E, F, and H, and this switchboard is forthe purpose of making or breaking all of the currents from thecontrollers to the motors, so as to throw the current off when theapparatus is out of use.

Z represents a platform to accommodate the operator, and upon thisplatform are located the controllers N, here shown as four in numher,one for each motor, in order that the entire operations of the devicemay be under the immediate control of the operator standing upon theplatform.

It is obvious that this immediate charger may be utilized in conjunctionwith a number of furnaces, the only requirement being that all of saidfurnaces are in a line in order that the charger-track may be broughtinto proper alinement with the doors thereof.

Having thus fully described my invention, what I claim as new and usefulis 1.
